چکیده
The seismic events that occurred in the last decades have highlighted importance of a correct design structures areas and inadequacy large part built heritage. Modern codes are still lacking terms prescriptions for evaluation performance existing buildings. present work proposes simplified method demand plastic rotation short links steel Eccentrically Braced Frames (EBFs). A relationship demand, exploits elastic analysis rigid-plastic extended to second-order effects, is proposed. calibration this was carried out on 420 EBFs equipped with designed according three different approaches. frames been also used analyze behavior range EBF type links. study provides an extensive influence redistribution capacity rotations links, corresponding achievement maximum bearing capacity. obtained relation can be exploited as assessment tool by comparing link Moreover, from performance-based point view, same predicting required ultimate function structure.

Proposing the simplified model for choosing the method of retrofitting in existing structures against fire risk
Background and objective: According to the necessities in the part 3 of National Building Regulations, design and construction of buildings should be in a way that the structures, according to the type of use, the size and the number of floors, resist long enough to fire, and prevent from destruction of buildings or from spread of fire to adjacent spaces or buildings. For this purpose, it is ne...
متن کاملNitrogen supply and demand in short-rotation sweetgum plantations
Intensive management is crucial for optimizing hardwood plantation success, and nitrogen (N) nutrition management is one of the most important practices in intensive management. Because management of short-rotation woody crop plantations is a mixture of row-crop agriculture and plantation forestry, we tested the usefulness of an agronomic budget modified for deciduous perennial trees for estima...
متن کاملOptimal Demand Response for Distribution Feeders with Existing Smart Loads
Load characteristics play an important role in distribution systems, which are traditionally designed to supply peak load; hence, decreasing this peak can considerably reduce overall grid costs. Basic components of smart grids such as smart meters allow two-way communication between the utilities and customers; in this context, controllable smart loads are being introduced, which allow developi...
